I have the same problem. I'm thinking I'll roll my Windows 10 machine back to version 12 and see if that works Seems like it's one issue after another with Teamviewer these days. Finally got the microphone pop-up windows issue resolved and now this. Wondering why I bother when I could just use DWService.net instead.

I also want to roll back to version 12, but it's difficult as the computer is my father's, several hundred miles away, and he's struggling with his vision.

I've decided that if there isn't a better solution, I'll use Chrome Remote Desktop to access his machine to roll back TeamViewer.

(It's all a bit silly — obviously, this wasn't tested properly before release. I specifically didn't want a beta version on his machine, so why on earth did it upgrade? Oh well, it's done now. I'll have to work around it.)

Just a thought here but I wonder if you have tried using DWService.net as an option to remote into your father's machine? If not, I recommend giving it a try. Personally, I'm not really familiar with Google Chrome Desktop and perhaps, if you are, that's your best bet but I thought I'd mention DWService as it's what I use having gone through a number of different remote desktop options. I used TeamViewer for a long time and it's still my fallback option should I have trouble but DWService has been great and is worth a look IMHO. Good luck.
